I first need to say this, if you liked Bastion you would love Transistor.
I played Bastion a couple of years ago and I thought it was brilliant. The only downsides were in my opinion the gameplay itself and the story. The combat felt out of date, and I forced myself through it because of the great atmosphere. The same with the story, it was not really believable that a little kid would save the world. But then again, the atmosphere was amazing and the thing that made Bastion one of my top gaming experiences.
Fast forward a couple of years to Transistor, take Bastion but take away all the bad stuff from it and you have Transistor. Supergiant games have thought up an interesting story and put in a very cool combat system, which is easy to learn but takes time to master. A lot of strategy is involved in the combat and to combine all of the different functions (moves) and see what happens was one of the games strong points. The atmosphere and music are top notch and the story is interesting. You feel for the characters, Red the heroine and also the talking sword. Who was he ? Can we save him ? Can we get our voice back ? What is happening in the city ?
A lot of questions pop ups the first ten minutes and I feel that they were all explained around 6 hours later. The story is brought to the gamer mainly by the swords voice, with some occasional reading on terminals. If you want to dwell deeper into the lore you can read about the different functions and who they were when they were alive. But to do so, you need to equip them in battle. A smart thing from the developers, leading to more experimentation of the different functions.
Great graphics, great story, great music, great atmosphere, great combat. Well, this is one of the best games I have played.
